Length of 50 hz
Hi all,
In responce to your question:
If you take the speed of sound @ sea level to be roughly 340 metres per second and you know that Hz is cycles per second. You would have 50 cycles over 340 metres.
So 340m divided by 50 cycles equals 6.8 metres (22.31 feet).
50hz = 6.8m, 60hz = 5.66, 70hz = 4.86 and so on.
Compact Bass Traps tend to work best in quarter cycles (1.7m)
